Chrysanthemum plant named ‘Yobarbie’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Yobarbie’, characterized by its compact, upright and somewhat outwardly spreading plant habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; medium-sized decorative-type inflorescences with elongated oblong-shaped ray florets; lavender-colored ray florets; and natural season flowering in mid-October in the Northern Hemisphere.

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Yobarbie’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially known as a garden-type Chrysanthemum and hereinafter referred to by the name ‘Yobarbie’.

The new cultivar is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Alva, Fla. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret colors and good garden performance.

The new Chrysanthemum originated from a cross-pollination made in March, 2001 in Salinas, Calif., of a proprietary selection of Chrysanthemum×morifolium identified as code number 98-M306, not patented, as the female, or seed, parent with the Chrysanthemum×morifolium cultivar Empire Symphony, disclosed in U.S. Plant Pat. No. 8,782, as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Alva, Fla. in November, 2002. The selection of this plant was based on its desirable inflorescence form, attractive floret coloration and good garden performance.

Asexual reproduction of the new cultivar by terminal vegetative cuttings in a controlled environment in Alva, Fla. since January, 2003, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Yobarbie has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yobarbie’. These characteristics in combination distinguish ‘Yobarbie’ as a new and distinct cultivar:

-   -   1. Compact, upright and somewhat outwardly spreading plant         habit.     -   2. Freely branching habit; dense and full plants.     -   3. Uniform and freely flowering habit.     -   4. Medium-sized decorative-type inflorescences with elongated         oblong-shaped ray florets.     -   5. Lavender-colored ray florets.     -   6. Natural season flowering in mid-October in the Northern         Hemisphere.

In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Chrysanthemum and the female parent         selection differed in ray floret coloration as plants of the         female parent selection had red bronze-colored ray florets.     -   2. Ray florets of plants of the new Chrysanthemum had better         color retention than ray florets of plants of the female parent         selection.     -   3. Plants of the new Chrysanthemum flowered about two weeks         later than plants of the female parent selection when grown         under natural season conditions.

In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the male parent, the cultivar Empire Symphony, in the following characteristics:

-   -   1. Plants of the new Chrysanthemum were more rounded than plants         of the cultivar Empire Symphony.     -   2. Plants of the new Chrysanthemum had smaller inflorescences         than plants of the cultivar Empire Symphony.     -   3. Plants of the new Chrysanthemum flowered about one month         later than plants of the cultivar Empire Symphony when grown         under natural season conditions.

Plants of the new Chyrsanthemum can be compared to plants of the Chrysanthemum cultivar Yodanielle, disclosed in U.S. Plant Pat. No. 13,802. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Yodanielle in the following characteristics:

-   -   1. Plants of the new Chyrsanthemum were larger than plants of         the cultivar Yodanielle.     -   2. Plants of the new Chrysanthemum were less sensitive to root         pathogens than plants of the cultivar Yodanielle.     -   3. Plants of the new Chrysanthemum flowered about five days         later than plants of the cultivar Yodanielle when grown under         natural season conditions.

Plants of the new Chyrsanthemum can also be compared to plants of the Chrysanthemum cultivar Gedi Two Cop, disclosed in U.S. Plant Pat. No. 14,404. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Gedi Two Cop in the following characteristics:

-   -   1. Plants of the new Chrysanthemum were larger than plants of         the cultivar Gedi Two Cop.     -   2. Ray florets of plants of the new Chrysanthemum had better         color retention than ray florets of plants of the cultivar Gedi         Two Cop.     -   3. Plants of the new Chrysanthemum flowered about two to four         days later than plants of the cultivar Gedi Two Cop when grown         under natural season conditions.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Leamington, Ontario, Canada during the summer in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial garden-type Chrysanthemum production. Rooted cuttings were planted in 15.25-cm containers, grown under artificial long day conditions (four-hour night interruption) and pinched about ten days later. About ten days after the pinch, plants were then exposed to artificial short day conditions (11.5 hours light) until flowering. During the production of the plants, temperatures ranged from 18° C. to 38° C. Measurements and numerical values represent averages for typical flowering plants.
